Context:
Approximately 11% of cancer survivors smoke postdiagnosis.
Objectives:
Understanding the relationship between smoking and perceived cancer-related symptoms may inform tobacco treatment interventions for this population.
Methods:
From 2017 to 2021, 740 adults in 9 ECOG-ACRIN trials provided baseline data. The effects of smoking status on symptoms were evaluated using logistic regression, adjusting for age, gender, race, performance status, treatment setting, and anxiety. Fisher's exact test was used to compare the prevalence of patients reporting that smoking helps/worsens each symptom by smoking status (current vs. former).
Results:
Among participants (mean age = 58.8, 93.9% white, 30.3% female, most common cancer types: leukemia [35.5%], lymphoma [19.1%], and prostate [17.7%]), smoking statuses were: 81 current (10.9%), 257 former (34.7%), and 402 (54.3%) never. Patients currently smoking were more likely to experience cough compared to those who formerly (OR = 3.25, P < .0001) or never (OR = 3.70, P < .0001) smoked. Current smoking was associated with greater severity of cough and pain and greater pain interference compared to former and never smoking (OR's > 2.26, P's < .005). Patients currently smoking were more likely to report that smoking helps with nausea (29.4% vs. 1.3%, P < .0001), insomnia (16.4% vs. 0.6%, P < .0001), and pain (16.1% vs. 2.8%, P = .002) compared to those who formerly smoked.
Conclusion:
Patients currently smoking report greater severity of cancer-related symptoms (i.e., cough, pain) yet were also more likely to believe that smoking helps with nausea, insomnia, and pain. Symptom management should include tobacco cessation, education on smoking and its relationship to symptoms, and strategies to reduce reliance on smoking for symptom relief.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
